tdf#133957 sw: SelectAll should select fly in empty section

Ctrl+A should select everything in the section; if the section is empty,
there's no text to select, and then the shell will cancel the selection
because SwCursorShell::HasSelection() returns false - so check if
there are flys anchored there, which fixes the Copy.

To fix Delete, a few more checks for empty selection need to be changed.
